Defoe's Robinson Crusoe-mere fiction or allegory?--need help!!!

[Neha Khan]

Hi friends,
I need your view of Defoe's Robinson Crusoe. Is it the allegory of defoe's life, a religous writing or a book on economics?
I want you to reflect upon it and give me some critical views on the book.

It is said that the novel is an allegory and symbolism of many things. http://www.shmoop.com/robinson-crusoe/sea-symbol.html

For me it is about nature and solitude to which the main character is forced, not chosen by his own will.
